SPECIFICATION forming part of Letters Patent No. 296,004, dated April 1, 1884:.

' Application filed November 22, 1883. (No model.)

Be it known that I, JOHN V. HAWKEY, a citizen of the United States, residing at Irwins Station, in the county of \Vestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Hubs for Car-Wheels, ofwhich the following is a specification, reference being had therein to the ac- .Companying drawings.

My invention relates to an improvement in hubs for car-wheels; and it consists in the combination of the protector which is placed on the axle, and which is provided with shoulders on its outer side and the oil-chamber in its outer end, which chamber has an inlet and outlet for the oil, with the axle upon which the protector is rigidly secured,and the-hub of the wheelwhich runs upon the protector,

I as will be more fully described hereinafter.

My invention is mainly intended for cars that convey the products of mines on narrow-gage railroads or tramways and on inclined planes to the tipple. The wheels on such cars are necessarily of small diameter, and consequently make many revolutions while onlyrunning short distances. The rapid motion of the wheels causes the axles soon to be worn away; and to prevent this I secure to the axle a protection in the form of a covering, around which the hubrevolves. This protector, when worn out, is easily removed from the axle and exchanged for a new one, and costs much less than the restoring of a worn axle. By the application of this protecting device with the required changes in the hub, an axle may be made to serve a great length of time without undergoing repairs, and when the protecting device is worn out it can be readily removed and replaced without the assistance of a skilled help. p

In connection with the protecting device for the axle and the hub, I have also found the means for oiling the same inwhatever posi- Iytion the wheel may be standing, preventing at the same time the spilling of oil when the wheels move rapidly.

The accompanying drawings represent my invention.

Figure 1 is a sectional view; Fig. 2, a plan. A represents an axle with a washer, B, bearing against the shoulder G. On the axle is a stationary cover or protector, D, confined between the washer B and linchpin E. The circumference of the protector D consists of aseries of fiat rings or planes, 1 2 3, adjoining one another, diminishing in width, but increasing in elevation toward the pin E, the lowest of them abutting against the washer B.

Surrounding the protector D is the hub D, whose inner surface corresponds inversely to that of 'D, with sufficient space between the planes to give play room to the hub D. The

hub is in contact with the protecting device at within the protector,-and a channel, J, leads the oil from the former to the places of contact between D and D. The-opening Gbeing stationary, oil may be poured in at any time without a possibility of its being ejected when the cars are in rapidmotion, since the oil, af-' ter it has entered the space F, remains also motionless, distributing only what is needed for lubricating the surfaces in contact.

Having thus described my invention, I clain1- The protector D, having shoulders 1 and 3, intermediate shoulder, 2, chamber F, opening G, and channel J, in combination with the described.

In testimony whereof I affix my signature in presence of two witnesses.
